A tiny gemstone outside the Paris hotel where Kim was targeted could provide vital DNA evidence which may lead cops to the attackers.

“A piece of stolen jewellery was found close to the block, and was presumably dropped by the gang. It suggests that the criminals may have made mistakes because they were in such a hurry,” a source close to the investigation told Mail Online.

The new information comes as it was revealed Kim has called in former special forces troops to spearhead her own probe into her Paris raid ordeal, The Sunday People can exclusively reveal.
